Question

A clock draws 2.0 watts of power to operate and is in operation 8,600 hours per year. The energy usage of the clock, in kWh per year, is closest to

Answer 1

the energy usage of the clock per year is 17.2 kWh

Step-by-step explanation:

Given;

power drawn by the clock, P = 2 W

duration of the clock's operation, t = 8,600 hours per year

The energy usage of the clock per year is calculated as;

E = Pt

`E = ((2)/(1000) )kW \ * \ 8,600 \ hr\\\\E = 17.2 \ kWh`

Therefore, the energy usage of the clock per year is 17.2 kWh
